Abstract

Quantum computers have data in the form of quantum bits (qubits), which are 0 and 1 simultaneously. This 0 and 1 state is the electron spin state on the quantum computer, namely spin up and spin down. Qubits are very sensitive to environmental disturbances, so it is necessary to accelerate the adiabatic dynamics so that the system's coherence is not disturbed by environmental interactions. These spin dynamics can be accelerated using the fast forward method, which uses an additional phase to drive the spin adiabatically. The adiabatic state is a state where the dynamics of a system have the same characteristics as the initial state after the dynamics take place. This research was conducted by qualitatively reviewing physical theory and conducting literature studies on previous research on the fast-forward method and the Landau-Majorana-Zener system. The results of this study obtained wave function solutions, regularization terms, and additional Hamiltonians in the Landau-Majorana-Zener system to accelerate adiabatic spin dynamics so that spin dynamics on quantum computers are not disturbed by the environment. After adding additional Hamiltonian adiabatic dynamics in the Landau-Majorana Zener system can be maintained but requires considerable energy. The magnetic field needed to create the same graph as the wave function graph before adding Hamiltonian, B0 = 100 Tesla. The energy required to accelerate the adiabatic spin dynamics is large, so the cost is also quite large. Therefore, efforts are needed to minimize the energy required to accelerate the adiabatic spin dynamics.

Abstract

This study aimed to predict Peak Ground Acceleration (PGA) values for the Bengkulu region using an Artificial Neural Network (ANN) model. The ANN model utilized earthquake parameter inputs, including magnitude, depth, and hypocenter distance, with soil PGA data collected from the Bengkulu City area. The PGA values were estimated using a neural network model, with the results optimized, validated, and evaluated for performance. The model accurately predicted PGA for large-magnitude earthquakes (R² = 0.99 for magnitudes 7.9–6.5). However, its performance declined significantly for smaller magnitudes (R² = 0.0141 for magnitude 4), reflecting challenges in accurately capturing input parameters, like focal depth and epicentre distance for low-magnitude events. Across a magnitude range of 4.0 to 7.9, the model achieved an overall R² value of 0.99, indicating high accuracy, particularly for larger magnitudes. However, the model's performance declined for lower magnitudes, with R² values dropping significantly, attributed to inaccuracies in input parameters, such as focal depth, epicentre distance, and period. The study provided logarithmic equations for each magnitude range tailored to the seismic characteristics of Bengkulu City, highlighting the importance of localized PGA prediction models. The findings suggest the potential effectiveness of the ANN model for improving earthquake early warning systems and seismic risk management in Bengkulu City under simulated conditions, particularly for large-magnitude earthquakes (R² = 0.99). However, the model’s limitations in predicting PGA for low-magnitude events (R² = 0.0141) highlight the need for further refinement before real-world implementation. This research contributes to the growing body of knowledge by validating and refining the ANN approach for region-specific seismic conditions, offering a practical tool for local authorities and disaster management agencies. Future research should improve the model's accuracy for low-magnitude earthquakes and explore hybrid machine learning techniques to enhance predictive.

Abstract

This research aims to determine students' problem-solving skills after using tournament-based online truth or dare media (New Todame). The effectiveness was measured at the implementation stage using a One-Group pretest-posttest design on 52 eleventh-grade IPA (Natural Science) students in one of the public high schools in Bandung City. The sampling technique employed was the purposive sampling technique. The testing techniques used were the normality test (Kolmogorov-Smirnov), the non-parametric Wilcoxon test, and the N-Gain test. Data collection was done by interview, preliminary study questionnaire, validation sheet, feasibility questionnaire, and pretest & posttest sheets. The results showed that the New Todame media was effective in improving students’ problem-solving skills on Newton's law material. The normality test (Kolmogorov-Smirnov) showed Sig. Value of less than 0.05, so that the Wilcoxon test was needed. The Wicoxon test results showed a significant difference in the average pretest and posttest, indicated by five aspects of problem-solving skills having an Asym.Sig value of 0.000. In addition, the increase in problem-solving skills on Newton's law material after students use New Todame media shows an N-Gain of 0.455 in the medium category

Abstract

Institut Teknologi Kalimantan (ITK) is one of the state universities that is currently actively developing educational facilities and infrastructure. Geologically, ITK is built on the Kampung Baru sedimentary rock formation, which has a low level of soil bearing capacity. This can cause damage to the building if the determination of the foundation depth does not have the right bearing data. The study aimed to determine the subsurface structure in the ITK campus area based on the speed of seismic wave propagation and to determine the distribution of subsurface hard rock layers in the ITK campus development area. The research methods used are field surveys, data acquisition, seismic wave recording data, travel time curves, 2D fast wave propagation models, and interpretation. The research results obtained the value of the first layer wave propagation velocity on tracks 1,2,3,4, and 5, ranging from 128.7 - 201.9 m/s. The second layer on tracks 1,2,3,4, and 5 ranged from 272.4 - 428.0 m/s. The research concludes that it can determine the subsurface structure based on the fast wave propagation value, geological conditions, and outcrop findings, namely the first layer in the form of soil and the second layer in the form of sand clay. Development can be carried out in the passive clay layer by laying the foundation

Abstract

Precision in radiation dose delivery is critical in cervical cancer treatment to ensure effective tumor control while minimizing damage to surrounding healthy tissues. Given the increasing adoption of advanced radiation therapies, comparative studies on dose distribution between different modalities are essential for evidence-based treatment planning. This study aims to compare the dose absorption in cervical cancer treatment using proton and gamma radiation through Monte Carlo simulation modeling. A Monte Carlo simulation was conducted using the Particle and Heavy Ion Transport code System (PHITS). Proton beams with an energy of 120 MeV and gamma rays at 30 MeV were applied from the anteroposterior (AP) direction using a pencil beam configuration (1 mm × 1 mm). Anatomical data were obtained from Digital Imaging and Communications in Medicine (DICOM) files sourced from RSUD Ulin Banjarmasin. Dose distribution was assessed in the target region and organs at risk (OAR). The results showed that proton therapy delivered a higher absorbed dose to the cervical target area (34.5 ± 1.5 MeV) than gamma radiation (16.7 ± 2.3 MeV). While both conformed to ICRU Report No. 78, gamma radiation resulted in higher doses to nearby organs such as the rectum and bladder, indicating a greater risk of radiation-induced side effects. Proton therapy offers more targeted dose delivery with reduced exposure to surrounding organs, making it a potentially safer and more effective modality for cervical cancer treatment. These findings underscore the importance of modality selection in optimizing therapeutic outcomes and minimizing complications in radiotherapy.

Abstract

Coal-fired power plants not only generate electricity but also produce coal ash containing naturally occurring radionuclides, which may pose radiological hazards to workers and nearby residents. This study aimed to assess the radiological risks associated with natural radionuclides present in coal ash and surrounding soil near PT Sugar Labinta, Lampung. To achieve this, samples of fly ash, bottom ash, and soil were systematically collected, and the specific activities of radionuclides radium-226, thorium-232, and potassium-40 were measured using gamma-ray spectrometry with High-Purity Germanium (HPGe) detectors. These measurements served as the basis for evaluating potential radiation hazards. The results showed that the gamma index values for fly ash (zero point seven seven seven), bottom ash (zero point three seven zero), and soil (zero point five one four) were all below the safety threshold (gamma index less than or equal to one), indicating low levels of gamma radiation and minimal radiological risk. Similarly, the external hazard index values ranged from zero point one two six to zero point six zero five, remaining under the recommended limit (external hazard index less than or equal to one). However, several samples, particularly fly ash (up to ninety-nine point zero two five nanogray per hour) and soil (up to sixty-five point five one one nanogray per hour), had absorbed dose rates exceeding the global average set by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). While most soil samples had annual effective dose equivalents below the standard limit of zero point zero seven millisievert per year, fly ash exceeded this value, signaling the need for continued monitoring, especially in residential areas near the power plant chimney. These findings suggest that coal ash and soil around PT Sugar Labinta generally present a low radiological risk. However, ongoing monitoring is essential to detect and mitigate potential long-term exposures. The study contributes valuable data for environmental radiation assessments and supports the implementation of effective radiological protection strategies in coal-fired power plant areas.

Abstract

This study aims to synthesize hematite based on magnetic minerals from the Geres River sand, which is used as a heavy metal absorbent. The Geres River iron sand-based magnetic mineral has a high iron content that can be extracted to produce hematite. The synthesis method used is the coprecipitation method. Mineral content and morphology were characterized using SEM-EDX. Hematite functional groups were analyzed using FTIR. Water quality analysis was based on physical parameters (conductivity and TDS) using a TDS meter, while the heavy metal content of Mn before and after filtration was analyzed using AAS. Based on SEM-EDX analysis, the average grain size of hematite was (0.99 ± 0.20) µm with the highest element content of Fe (72.90 ± 0.28) %. Functional groups are formed at a wavelength of 951.72 cm-1, which shows the Fe=O double bond. After filtration, hematite was able to reduce the heavy metal content of Mn by 19.58%, followed by a decrease in conductivity by 12.95% and a decrease in TDS by 15.18%. This shows that hematite is effectively used as a heavy metal absorbent. Through this research, it is hoped that the community will not only use iron sand magnetic minerals as building materials but also process them into more useful materials such as hematite, which can be used as a heavy metal absorbent.

Abstract

Physics learning often faces challenges in improving students' conceptual understanding. Conceptual change models are widely used to address this. This study aims to analyze these gaps, review the materials used, and identify improvements made. The study examined fifty-seven articles from four good-quality journal databases: Scopus, Science Direct, Eric, and Sage Journal. This study uses a systematic literature review method using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) technique. The analyzed data was visualized based on selected articles in the form of mapping tabula, including the country of origin of the research, the physics content studied, the frequency of topic material, and the focus of the problem in the research over the last five years (2019-2024). The findings show that the trend of applying learning models in various physics learning materials over the past five years has varied, with ten countries implementing conceptual change model research. The content of matter has varied, including complete kinematics, fluids, pendulums, temperature and heat, sound waves, light waves, Pascal's laws, and quantum. The benefits of integrating conceptual change models in physics learning include diagnosing students who experience misunderstandings and improving conceptual understanding. One of the next research recommendations is to apply momentum and impulse materials while still using a conceptual change model in physics learning.

Abstract

The performance of ZnO-based nanostructured photodetectors has garnered significant interest due to their potential for high sensitivity and fast response in ultraviolet and optoelectronic applications. This review aims to comprehensively analyze recent advancements in enhancing ZnO photodetector performance through single doping and codoping strategies. This study synthesizes findings from peer-reviewed research articles published over the past five years. The results indicate that specific dopants, such as F, Mg, Ti, and Co+Ni, significantly improve key performance parameters, including responsivity, sensitivity, and detectivity. Codoping approaches, particularly with In+Ga or Sn+Ti, exhibit synergistic effects that further enhance carrier mobility and reduce trap states, resulting in external quantum efficiencies exceeding 10⁹%. The review concludes that the careful selection and concentration of dopants, nanostructure design, and scalable fabrication methods are crucial for optimizing ZnO-based photodetectors. This work contributes by offering a structured synthesis of performance trends, identifying research gaps, and outlining future directions for developing high-performance and industry-ready ZnO photodetector technologies.

Abstract

longer optional but essential. As students navigate an era demanding innovation and problem-solving, teachers must rethink how learning happens. This study explores the effectiveness of problem-based blended learning (PBBL) in enhancing creative thinking skills among students aged 15-17. The study employs a quasi-experimental design involving both experimental and control groups, with a pre-test and post-test approach. A purposive sampling technique selected 40 students within the target age range. Students’ creative thinking was assessed using an essay-based instrument aligned with the PISA 2021 Creative Thinking Framework, which focuses on generating diverse ideas and creative ideas and evaluating and improving ideas. The results reveal that PBBL has a significant impact, as indicated by a high effect size tested using Cohen’s d formula of 0.9 on the post-test results. These findings suggest that problem-based blended learning is an effective strategy for promoting creative thinking skills in adolescents and may serve as a valuable approach for future educational practices.
